Yeah, there is a sign between the two terminals, labeled "meeting place"... impossible to miss.

If I'm not mistaken, I've seen more than one "meeting place" between the two terminals. In any case, they are cold in the winter without comfortable seating arrangements. The maglev area is convenient if you're going to take the maglev, but if you're going to fly out of one of the two terminals, look at a map and select a restaurant at the best spot.

So, I ended up meeting her at the customs exit...easy, there's only one way out This would be my recommendation for anyone in such a situation. I guess the meeting point can be a backup plan.

Free wifi was tough, but cheap wifi (the price of fries) was easy at...I think it was Burger King? The password was a very tough 1234567890 and may be the same for all of the eating establishments using the same service.
